Checkit Comparator D 55 with mirror optics, layer depth 55 mm

Test with the color disc in many areas of application
CHECKIT® Comparator Test Kits are precise, easy-to-use test kits for water analysis. Simply add the reagent to the cuvette, rotate the disc until the color matches the prepared water sample, and read the concentration value.

Step-by-step instructions: Multilingual instruction manuals provide illustrated step-by-step instructions on how the test is carried out - so that even non-chemists can carry out reliable and accurate measurements quickly.
Large selection of parameters: Several measuring ranges and methods are available for many parameters. Additional test parameters can be added by purchasing additional discs and reagents - you use the same comparator housing for all tests.
One-piece comparator housing: The robust design of the one-piece comparator housing has no "moving parts" that can be lost or broken. Simply slide the color disc into the housing until it clicks into place and you're ready to test. The test results will be easy to read in the results window.
Easy to read results: The diffuser panel on the back of the CHECKIT® Comparator housing helps distribute light evenly between the two cuvettes. This makes it easier to achieve accurate color matching and helps the user to visually compensate for any cloudiness in the sample.
Continuous color gradient: CHECKIT® discs have a continuous color gradient, allowing direct color matching - the result does not have to be between two color standards be extrapolated.
